The lsprpc package needs to wait on the newly bound connection to
perform some tear-down, so it must be safe to call conn.Wait from Bind.
Achieve this by switching async from an init pattern to a constructor.
This means moving async fields to pointers, but since they weren't safe
to use prior to initialization anyway this feels correct.

Allow users to experiment with golang/go#45713 by adding experimental
support for the go.work file. We handle it like a special case, very
similar to the current gopls.mod file mechanism. The behavior is
undefined if both a gopls.mod and go.work file exist. Ultimately, we
will deprecate support for the gopls.mod file if the go.work file
proposal is accepted, so I don't think it's important to be careful
about handling both simultaneously.

Retrying CL 271477, this time with parts of CL 322650 incorporated.
This CL moves to a model where we don't automatically delete invalidated
metadata, but rather preserve it and mark it invalid. This way, we can
continue to use invalid metadata for all features even if there is an
issue with the user's workspace.
To keep track of the metadata's validity, we add an invalid flag to
track the status of the metadata. We still reload at the same rate--the
next CL changes the way we reload data.
We also add a configuration to opt-in (currently, this is off by
default).
In some cases, like switches between GOPATH and module modes, and when a
file is deleted, the metadata *must* be deleted outright.
Also, handle an empty GOMODCACHE in the directory filters (from a
previous CL).

wouldn't correctly invalidate broken package metadata when a problematic

Fix this by invalidating any broken packages when an import path is

problems with trying to do better.

"type mod" refers to agglutinative expressions such as dereference
"*", invocation "()", and slicing "[:]". When considering an object as
a completion candidate, we check whether applying a type mod would
make it a better candidate.
Previously we tracked the type mods we wanted to apply to a candidate
by setting bool fields. Now instead we keep a slice of the type mods.
This has two main advantages:
- The mods are now ordered which will allow us to format candidates
properly when the same mods can appear in different order (e.g.
"<-*foo" or *<-foo").
- We can now record any mod multiple times allowing for "<-<-foo" or
"foo()()".
I changed the formatting code to always create a snippet object since
that made things simpler. I had to tweak a few snippet helper methods
to accept a snippet argument rather than creating a new snippet.
This commit's only functional change is that we no longer show any
type mods in candidate labels. For example, the user will now see
"foo" in the completion popup instead of "*foo". Showing the operators
adds noise to the candidate list, and we didn't display them
consistently.

This is typically not a problem when we are picking out the widest or

The two codelenses that are attached to the module statement are
'Run go mod tidy' and 'Create vendor directory'. In a 'go.mod' file
without any required modules, the only codelens that shows up is
the 'Create vendor directory'. With no required modules, there is nothing
to vendor, but 'Run go mod tidy' may actually clean up the go.mod and go.sum,
so this is the codelens we want to appear.

For example:
type foo struct { i int }
type bar struct { i int }
var _ foo = <>
Previously at <> we would offer "bar{}" in addition to "foo{}" because
we knew "bar" was convertible to "foo". The "bar{}" completion wasn't
valid as inserted, however, because we didn't include the type
conversion. Anyway, it doesn't make sense to include convertible types
since the directly matching type should also be available. Fix by
tweaking the literal candidate code to skip candidates requiring
conversion.
Fixesgolang/go#46113.

- Use func.FullName() everywhere we can, since simply Printf or Errorf is often ambiguous.
- Give more specific error output when unsupported %w directive is used.

The old code mistakenly presumed all clients would want the standard
set of semantic tokens in the LSP specification, but clients have the
option of asking for fewer, so gopls should only use those.
